Celine Dion Played the ABC’s With Naming Twins, Eddy and Nelson

She may not have trouble hitting those high notes when she sings, but when it came time to naming her newborn twins, Eddy and Nelson, Celine Dion had a bit of a struggle on her hands.

On Monday's 'The Oprah Winfrey Show,' Dion admits to calling her sons Baby A and Baby B for the first week of their lives. "[My husband] René said, 'Listen, people are starting to call me. What's their names?' " Dion tells the talk show host. "'I can't tell them A and B again – that's not working.' "

The singer, 42, contemplated using different letters, saying the nicknames were getting to be a bit confusing for them and their 10-year-old son, Rene Charles. "It's like, 'Was the hat switched? I thought this was Baby A,'" she jokes. "And I'm like, 'Stop [with] the As and the Bs. I'm going to do C [and] Ds right now. My name is Celine Dion with a C and a D, so don't push me because I'm close to the edge!'" (editor's note: It is unclear whether master beat-boxer Dion was intentionally quoting Grandmaster Flash or not at this point..)

Now four months old, her new sons have their appropriate names and are getting settled into their Jupiter Island, Fla. mansion, but not for long. Dion is gearing up for her next career venture, making her way back to Las for a new residency at the Colosseum in Ceasars beginning on March 15.
